Title: Apparatus for the reproduction of a twodimensional vector
IPC: G01C19/28
Filed: 1971-12-22
Abstract: 1335490 Co-ordinate transformers FRIED KRUPP GmbH 22 Dec 1971 [23 Dec 1970] 59731/71 Heading G4G [Also in Division G1] An electromechanical apparatus for resolving a given vector in an arbitrary co-ordinate system, comprises means for setting up the vector as an electric field in an electrolyte and an angularly adjustable sensor arrangement for determining the resolutes of the vector along axes determined by the angular adjustment. Electrolyte 3 is contained in an insulating vessel 4 in the walls of which are arranged two orthogonal pairs 5.1.1, 5.1.2 and 5.2.1, 5.2.2 of electrode arrays which receive voltages 1, 2 representing the resolutes of the given vector 6 in a Cartesian co-ordinate system determined by the electrode arrays. A pivoted rotary sensor 7 immersed in the electrolyte 3 is provided with four electrodes 8 defining a second system of rectangular coordinates having an orientation determined by the angular adjustment of the rotary sensor. Voltage signals from electrode pairs 8.1, 8.2 and 8.3, 8.4 are fed respectively to pairs of annular electrodes 10.1.1, 10.1.2 and 10.1.3, 10.1.4 arranged opposite respective pairs 10.2.1, 10.2.2 and 10.2.3, 10.2.4 of fixed pick-up electrodes. Voltages 11, 12 represent the resolutes of the vector 6 in the second co-ordinate system. The orientation of this system may be determined by a magnet 13 which aligns one coordinate with magnetic north. An unbalanced electrical system may be used in which the centre of the rotor is connected to system earth, in which case only two electrodes 8 are necessary. A suitable physical arrangement of the rotary sensor for an unbalanced system is described (Fig. 3, not shown). The electrodes may be arranged to define non-rectangular co-ordinates. The rotary sensor may have buoyancy to reduce friction in the conical bearings.

Title: A system for optimizing material utilization
Inventor: DOYLE H W
IPC: A41H3/00
Filed: 1969-12-08
Abstract: 1,241,738. Digital calculating. CALIFORNIA COMPUTER PRODUCTS Inc. 8 Dec., 1969 [30 Dec., 1968], No. 59817/69. Heading G4A. A digital computer is programmed to arrange a number of patterns within a predetermined area. The co-ordinates of the vertices on the perimeter of a pattern to be placed are stored together with the co-ordinates of the vertices on the perimeter of a marker boundary which is defined by the patterns which have already been placed in position and information indicating whether the stored vertices are concave or convex with respect to adjacent vertices. The computer then modifies the pattern perimeter co-ordinates progressively in a manner corresponding to movement of the pattern so that it is in contact with but does not overlap the marker boundary until the pattern lies wholly within the predetermined area and increases a given dimension of the marker boundary by the smallest amount. The co-ordinates of the marker boundary are then updated to include the last positioned pattern. The operation is described by the flow drawing illustrated in Fig. 5. The co-ordinates of the pattern to be placed are operated on, step 507, so as to place the pattern in the standard starting position, a, Fig. 9. The order in which patterns are presented for placement is predetermined and the patterns are not twisted or turned during placement. The pattern may be " moved " along either the edge of the marker boundary or along one of its own segments, i.e. " flipped " end through end whilst it is in contact with a vertex of the marker boundary, see Fig. 9 positions c and d. The movement is made along the marker boundary edge if the gradient of the next counterclockwise segment of the boundary is less than that of the segment of the pattern to the left of the contacting vertices and along the pattern edge in the converse case. The movement to be made is determined by calculating the cross product of the two vectors representing the boundary and pattern segments. In the case of a concave vertex on the boundary edge the pattern may not be moved along the whole length of the segment of the boundary edge since it may overlap the boundary at some point. To avoid this interference a calculation is performed, step 512, Fig. 5, to determine whether the proposed displacement of the boundary vertex will cause the segments of the pattern and boundary to intersect. The maximum allowable displacement is then calculated by solving vector equations. To reduce the amount of computation required to perform the vector algebra a number of tests are performed to eliminate non-interfering vertices before the full vector computations are made on the remaining vertices.

Title: Calendar timepiece
IPC: G04C3/14
Filed: 1978-07-10
Abstract: An analogue quartz crystal calendar watch is provided with automatic date adjustment at the end of a month having less than 31 days by arranging that a date wheel 7 sends a feed-back signal at the end of a month to an integrated circuit 2 which is programmed with calendar information. This calendar information is compared with the date indicated on the date wheel 7 and, if there is disagreement, the integrated circuit 2 supplies signals to stepping motor 3. The latter then undergoes, at least once, a successive reverse and forward drive at a speed substantially greater than its normal operating speed so that the time indicating hands 5 are adjusted a corresponding number of times through a predetermined time period during which calendar adjustment occurs, and the date wheel 7 is simultaneously adjusted to indicate the first day of the next month. For checking, the month may be indicated by an LED display visible through the notches in a day star wheel. <IMAGE>

Title: Program-indicating device
IPC: D06F103/38
Filed: 1979-02-14
Abstract: A domestic appliance H has a program display panel T comprising visual display elements E each corresponding to a particular operating step. When the program is selected using a keyboard or other selector P, the program controller ST activates all the display elements E corresponding to steps in the selected program. As the program runs, the controller ST deactivates the display elements in succession, as the corresponding steps of the program are completed. Consequently the initial display shows what steps form the program, and during operation the display shows what step is currently running and what further steps remain to be performed. The final display element may remain activated when the program ends. <IMAGE>
